LkCa 15 c
LkCa 15 c orbits the star LkCa 15, 515.8 light-years from Earth.
Get to know this world ↓Size-based classification; composition may be uncertain.
Its light travels for roughly 516 years to reach us.
Imaging
Overview
LkCa 15 c is one of the confirmed worlds in the NASA Exoplanet Archive. Recorded as discovered in 2015. The credited discovery facility is Large Binocular Telescope Observatory. Its Imaging evidence gives us a way to study a planet that is usually too faint to see directly.
Its radius is not currently available in this catalogue, so we leave its size class unassigned.
The planet
A reliable mass is not available in this record.
Mass and radius constrain possible interiors; multiple compositions can fit a given set of measurements.
Orbit & year
The orbital period is not determined in this record. Its recorded semi-major axis is 18.6 AU. One AU is roughly the Earth–Sun distance.
Host star
Effective temperature: 4,194 K.

How these methods work ↗Potential habitability
The data here does not establish habitability, liquid water, or life. An appropriate atmosphere and many other conditions would be needed.
The listed equilibrium temperature is 59 K. This is an estimated energy-balance temperature, not a measured surface temperature.
Understand the habitable zone ↗What do we actually know?
The underlying light, motion or timing signal. Usually not a photograph of the planet.
Parameters derived from observations, with instrument and model uncertainty.
Our light-year conversion and browsing class are calculated from archive values.
Equilibrium temperature is an energy-balance estimate, not surface weather.
Possible composition depends on models and may not be unique.
Surface conditions and the presence of life are not established here.
Measured signals are interpreted through models. The archive’s composite table combines published values and may include calculated estimates. Values do not necessarily form one self-consistent solution.
Radius and mass can be estimated or inferred, orbital period comes from recurring observations, and size classification is calculated by this site. Atmospheric and surface conditions remain unknown unless established by specific observations.
Consult the archive for individual parameter references and uncertainty intervals before scientific use.
